By pressing a button we'll activate a special view which will put a different colour to "interesting" elements in the environment: the background and non relevant objects will be shown in shades of grey and the clues in yellow. That way we'll be able to follow traces normally invisible to the eye, for example the footprints of the wolves which will lead us to where they have left the med-kit.

How do you feel about this feature? It reminds me of Batman's 'Detective Mode' (which is cool) and I especially love it because it is entirely optional. You can decide yourself if you want to keep searching on your own or enable this mode to get a hint. This way, there will be no need to make interesting parts of the environments stand out all the time by making them 'shiny'. Legend had something similar with the binoculars, but it wasn't implemented that well, since there were still icons and shiny objects all over the place.

As long as it stays optional, I'm fine, ergo, I don't like it and will not use it. It reminds me of Legend RAD mode of the Binoculars.

Jay already confirmed this as optional.

Everyone should be happy. It allows for help system for inexperienced/impatient 'casuals' while keeping the standard vision clean and non-shiny/spoilery. Nowadays, games simply cannot be shipped without any sort of help system. The gaming audience changed (for the worse) and unfortunately, to remain succesful Tomb Raider franchise needs to cater to them too, hence the helping system. Implemented this way is the best possible solution making everyone happy.
